Abstract
Aspects of the present invention include method and systems or processing multimedia data exchanged between mobile devices. Initially, a transmitting mobile device attempts to send multimedia data formatted in a primary format even though a receiving mobile device cannot process the data. The multimedia data in the primary format is then uploaded to a multimedia communication server where the multimedia data can be transcoded on demand into a secondary format that the receiving mobile device can indeed process. To track the multimedia data, the transmitting mobile device receives a multimedia identifier associated with the multimedia data uploaded to the multimedia communication server. Instead of sending the multimedia data, the transmitting mobile device forwards the multimedia identifier to the receiving mobile device allowing the receiving mobile device to demand transcoding the multimedia data into a secondary format on the server that the receiving mobile device is capable of receiving and processing.
